黑角直缘跳甲是五倍子夏寄主盐肤木和红肤杨的重要食叶害虫,一年一代,以卵及卵块在寄主枝干上越冬,次年4月当寄主幼芽萌发达3cm,叶片尚未完全展开时孵化。幼虫期4—5月,蛹期5—6月,成虫期6—10月,卵期9至次年4月。幼虫始见期随不同年份和不同海拨而异,物候期明显。数量消长与天敌和降雨密切相关。本文首次报道了该虫的生物学特性,并提出人工灭虫和保护天敌的防治措施。
Pointed black edge of the hopper is a gallnut summer host Rhododendron and red clover important leaf-feeding pests, a year, with eggs and eggs in the host branch of the winter, the following year in April when the host sprout germination up to 3cm, Hatching when leaves have not fully expanded. Larvae from April to May, pupa 5-6 months, adult stage 6-10 months, oviposit 9 to April next year. The initial larvae vary with different years and different altitudes, phenophase obvious. The decline in quantity is closely related to natural enemies and rainfall. This article first reported the biological characteristics of the insect, and proposed artificial pest control and protection of natural enemies.
